Fotis Panagiotopoulos 880d78f903 sendfile: Fixed behavior of sendfile when count is set to zero. 
If sendfile() is called with a zero count, it will nevertheless
try to send the data. This is mostly meaningless, it causes
waste of resources, and in some cases delays.

This commit adds special handling for this case, allowing
sendfile to return immediately zero. The new behavior is
in line with the Linux variant of sendfile.
